To all whom it may concern:

Be it known that I, JOHN JANIoKI, "a citizen of the United States,residing at Oak Park, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Methods of and Apparatusfor Serving Material upon a Core,

of which the following is a lull, clearyconk .cise, and exactdescription.

This invention relates to methodsof and apparatus for serving materialupon a core, and. more particularly to a method "of and apparatus forsimultaneously serving a plurality of strands upon a core. Y

In insulating wire for electrical purposes it is frequently thepractice'to'serve the wire core with a plurality of strands of silk, cotton, orother'insul ati'ng materials, which to expedite the serving operationhave been assembled into a band or a composite or multi-end strand andwound into a cop. The individual strands,whic h may be-different'lycolored to comprise an identifying covering for the wire, are arrangedtoform a single layer as they are served'u'pon the core. 'It has beenproposed'in one instance, that these strands be separated or fannedalongthe axis of the core and served thereon from a commonline disposedradially'with respect to the core. However, it hasbeen found that only alimited number of strands may be satisfactorily and uniformly served ina .simultaneous manner by such amethod. I V

The objects of the invention are to provide an improved method of and animproved apparatus for rapidly and uniformly serving an unlimited numberof strands upon a core.

In order; to attain this object in accordance with one embodiment ofthis invention, a plurality of strands are withdrawn irom a cop or othersupply toa common point, or a multi-end strand is drawn thereto, whichpoint is located at a distance from r the periphery of a core to beserved. The

strands or the ends composing the multi-end strand, are fanned from thecommon point p to a plurality of non-uniformlyspaced points sodistributed 'as' to 'mainta inthem separated. They are individua lly'guided therefrom to a corresponding numberfof points uniformly spaced"around core and then served to .theeore at substantially eqae 'aaglesto iQrl $l! aii ih In one embodiment of the invention in. an

apparatus byime'ans of which the method may be practiced, a. serv ngmechanism of a usual type wherein a core is drawnvertically through theaxisof a horizontally rotating holder and serving head from which thestrands are-served, is provided with a distributing head or platesecured to the The distributing plate is prov ded w th 'a plurality ofslotted apertures, the bottom or inle-t ends of which are non-uniformlyspaced. to maintain the,

strands fed from a common point separated from each other and from theserving head, while the upper or outlet ends of theaipertures areuniformly spaced aroundlthe core.

i'lhe rotat ion ofthehead serves the strands from the outletends of theapertures at substantially equalangles to'the core.

Other objects and advantages of this invention will more fully appearfrom the accompanying detailed description taken in connection with theaccompanying drawings which illustrate one embodiment thereof, in vhiFigfl fis 'afvertical sectional view partly .in elevation through aserving head embodying the features of this invention FigLjQis a planView thereof;

"The'tiibefifl is secured provide adesired tension upon the strands 19 during the operation of the servingmechanism.

Y The extreme threaded upper end of the spindle extends above the top ofthe rim 11 and is tapered, as indicated at 27 and provided with aplurality of slots, one of which is shown at 23, extending downwardlyfrom the end thereof. Adapted to be mounted upon the hollow spindle is aunitary multi-strand guiding device 29, a sleevelike portion 30 at thelower end thereof being being inserted in thebore of the hollow spindleand clamped thereto by turning a threaded collar 31 downwardly upon thetapered end of the spindle 15. The upper end of the device 29v comprisesa circular shaped head or plate 32 provided at its underside with acone-like. face'33 extending from the peripheral edge thereof to theperiphery of the sleeve-like portion 30. The upper face of the head 32is also provided with a cone-like face 34 whiclrextends from a pointinside the peripheral edge of the head 32 to the wall of the bore formedin the device 29. The purpose of the cone-like faces 33 and34 will bemade clear as the description progresses. The head 32 is provided in thepresent embodiment of this invention with seven angularly-disposedapertures 37 one for each of the strands 19, which apertures at theiroutlet ends upon the upper surface of the head 32, are equally disposed,radially and circumferentially with respect to a core 38 beingservedwhich serves to direct each strand to a certain predetermined point uponthe periphery of the core 38. The apertures 37. are formed at such anangle to the axis of the device and to each other that the inlet ends ofthe apertures are not equally disposed radially and circumferentially.-Theangle of each aperture is such that each strand 19 will be guided inpassing from the opening 12 in the rim 11 to its respective aperture 37and upwardly therethrough and to the core 38 being served withoutengaging any other strand during its travel. Also the-strands are guidedso that they will not contact with the periphery of the sleeve-likeportion 30 and due to the cone-like faces 33 and34, the guidingsurface-of the apertures is .reduced and consequently friction upon thestrands is reduced to a minimum. 'lof acili- 19 within an aperture 37 inthreading the serving mechanism by merely pressing the strand againstthe periphery of the head 32 between the slots 40 and slide it towardthe cut back portion 41 which will cause it to ride into the slot 40 andtherealong intothe aperture 37.

It will be observed that the diameter of the device 29 is such that acop 14 of serving material may be mounted on the serving mechanismwithout removing the device, the diameter being such that the tube 20carrying the cop 14 may pass freely thereover.

Referring to Figs. 1, 3 and 4 it will be noted that the strands 19 inpassing-from the opening 13 in the rim 11 to the core 38 do not engageeach other or any portion of the guiding device 29 except the walls ofthe apertures 37 and their engagementtherewith is reduced to ainininiuin due to the cone-like face 33 at the underside of the guide 29which serves to reduce the length of the apertures and consequentlyfriction upon the strands. After the strands 19 leave the apertures 37there occurs a point contact of the strands with the upper peripheraledge of the cone-like face 34 which with the uniform radial andcircumferential spacing of the outlet ends of the apertures 37 about thecore 38 serves to support and cause the strands to approach theperiphery of the core atuniform angles and laid thereon parallel to eachother.

The operation of the serving mechanism hereinbefore described is asfollows:

The core 38 being served, it will be understood, is drawn through thehollow driving spindle 15 and guiding device 29 by any suitable drawingoff mechanism which will insure an even steady movement bearing asubstantially fixed relation to the speed of rotation of-the drivingspindle and the diameter of the strand being served to the core. Drawingoff mechanisms of this type being well understood in the art, no attempthasbeen made to show the same. Upon mounting the cop 14 upon the sleeve16 in the manner hereinbefore described the end of the multi-end cottonstrand 18 is threaded through the openings 12 and 13 in the rim- 11 asclearly shown in Fig. 1. Upon leaving the opening 13 it will be readilyapparentthat the ends 19 of the strand 18' willbe separately guided tothe core 38 by their passage through the apertures 37 of the device andas hereinbefore explained lOJ ' guiding a plurality of strands from acom due to the uniform radial and circumferential spacing of the outletends of the apertures 37 about the core 38 they will be served with aminimum amount of friction and laid parallel thereon with a uniformtwist or lay.

A strand guiding device embodying the features of this inventionprovides for accurate control of the spacing between the strands as theyare served to the coretherc by preventing open spaces therebetween and,

piling up of one strand upon another.
